you can honk at people. In this Robot‚ we use the Linksys WRT54GL router. It’s very friendly in that it runs Linux and some of the hardware has been reverse engineered. A bunch of alternative firmware versions have been written for this router. The version that this project uses is the customizable Linux firmware Open-WRT. Along with great software for this router‚ a bunch of hardware are possible. With a cheap‚ embedded Linux system at our disposal‚ we knew we had to do something cool with it. So the
